We’ve reviewed 5 solutions to replace it below.

The app combines various means of communication: email exchange, instant messaging, voice mail, phone calls, etc. It is used by more than 500 million businesses and home users around the world. If you’ve chosen this option, you will need the Thunderbird to Outlook converter like to perform easy and smooth migration.

2) Gmail

Gmail is one of the most famous email services at the moment. The user is provided with 15 GB of storage place to work with correspondence, store private files, etc. It provides users with advanced spam blocking features and mobile access. Custom color labels allow you to neatly organize emails, automatic sorting of specific letters, etc. The user can access Gmail using a secure web interface or through the POP3 or IMAP4 protocols.

3) The Bat!

The main tasks of The Bat! are maintaining the confidentiality of correspondence, convenience, and time-saving when working with mail. It will protect your information using various methods, including encrypting user data on the hard drive and by using SSL/TLS protocols. Your emails are stored on your PC and not in cloud storage where they can be accessed by unauthorized users.

4) Mailbird

This is a new mailing program that has gained a reputation of a powerful app that is designed to be fast and easy to use. The reason Mailbird is a nice Thunderbird alternative is its ability to integrate a large number of third-party applications.

5) Postbox

This is one of the easiest to use email programs on this list.

Here you have emoji support, 25 email signature templates, and 70 unique reply templates at your service. Postbox also provides many integration scenarios with services like Slack, Evernote, Todoist, and others.


Whether you are a current Thunderbird user or someone interested in other options, there are many decent alternatives to it. If you rarely use mail, Postbox, Inky, or even webmail might be your best bet. For more advanced users, Mailbird or eM Client is suitable.
